Meta key prefixes

There are some key prefixes that provide metadata. Generally they are about the specific key, but sometimes they are about the whole object they are tagged on. They generally go before any other prefixes.

Here's a (probably incomplete) list of them:

Key prefix	Description
check_date:*=*	When this key was last checked
indication:*=*	This object indicates the presence of a (generally un-mapped) other object which would (if it was mapped) be tagged with this tag (key and value).
note:*=*	Information for other mappers about the tagging of this key on this object
source:*=*	Where the value for the key came from
